[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0027] like Figure 1 As shown, this application discloses a high-efficiency corn irrigation device including a nozzle angle adjusting arm 1, a water flow distributor 2, a fixed support frame 3, an adjustable nozzle 4, and a connecting hose 5. The nozzle angle adjusting arm 1 is hinged to the fixed support frame 3 via a rotatable connecting part. Its main body adopts a nested sleeve-type telescopic structure 11, and its end is equipped with a knob-bolt type fixing and locking mechanism 13. For example, an aluminum telescopic rod with a threaded locking pin 8 can be used to achieve length adjustment. The water flow distributor 2 is fixed at the middle section of the nozzle angle adjusting arm 1. It has a water distribution chamber and an electromagnetic control valve inside. A typical embodiment is a multi-port pipe fitting made of engineering plastic injection molding, connected to the adjusting arm via a flange. The fixed support frame 3 adopts a triangular support structure with spiral ground nails at the bottom. For example, it is a frame structure welded from galvanized steel pipe with a rust-proof surface treatment. The adjustable nozzle 4 is installed at the end of the nozzle angle adjusting arm 1 via a threaded interface. It has an adjustable guide vane inside, and can specifically be a rotating nozzle assembly made of brass. The connecting hose 5 is made of braided reinforced rubber tubing and is equipped with quick connectors at both ends, such as clamp-type connectors, to form a detachable connection with the dispenser and nozzle.

[0028] The nozzle angle adjusting arm 1 achieves 360° directional adjustment via a rotatable connecting part 12. This connecting part employs a universal joint structure with an internal damping bearing to maintain smooth rotation. For example, a stainless steel ball joint structure with a PTFE bushing can be used. Its telescopic structure consists of inner and outer double-layer sleeves. The inner sleeve has equidistant positioning holes, which, along with a spring pin, achieve segmented length locking. In a typical implementation, the inner wall of the sleeve is textured with anti-slip grooves to enhance structural stability. The fixing and locking mechanism 13 uses a screw-type handle design with a rubber friction pad at the end. Once adjusted to the correct position, radial pressure is generated by tightening the screw to achieve fixation.

[0029] The water distributor 2 has an internal flow equalization chamber, which is divided into multiple independent flow channels by partitions. Each flow channel outlet is equipped with a pressure compensation device, such as a flexible diaphragm pressure regulating valve, to ensure balanced water pressure in each branch. Its top housing has a mounting flange that connects to the support platform of the adjusting arm via bolts, and the bottom has a pre-installed standard pipe thread interface for connecting to external water supply pipelines. The distributor control panel integrates a wireless receiving module, allowing remote control of the opening and closing status of each branch valve.

[0030] The fixed support frame 3 features a foldable design, with multi-stage telescopic sleeves on the legs. These sleeves are locked together by spring clips, forming a stable triangular support surface when unfolded. A ring-shaped mounting base is welded to the top of the frame, which is bolted to the rotating connection of the adjusting arm. The mounting base contains embedded rubber shock-absorbing pads to reduce vibrations caused by water flow impact. The bottom spiral ground stakes have a tapered thread structure and are nitrided to improve wear resistance. In typical implementations, the stake length is designed to be 300mm to accommodate loose soil conditions.

[0031] The guide vane of the adjustable nozzle 4 has its deflection angle changed by rotating the adjusting ring. An angle scale is marked on the outside of the adjusting ring. The guide vane is made of stainless steel sheet, stamped and formed, with rolled edges to prevent water splashing. The nozzle base has a sealing groove with a nitrile rubber O-ring installed inside, forming an axial seal with the outlet at the end of the adjusting arm. The nozzle array uses a tapered design, with the orifice diameter gradually decreasing along the water flow direction to maintain spray pressure.

[0032] The connecting hose 5 adopts a three-layer composite structure: the inner layer is food-grade rubber, the middle layer is an aramid braided reinforcement layer, and the outer layer is covered with a UV-resistant PVC coating. Both ends of the hose use stainless steel quick-connect plugs with internal self-locking check valves that automatically seal to prevent backflow when the hose is under pressure. The hose length is designed to be flexible and adjustable, allowing free extension within a range of 2-5 meters.

[0033] This device addresses terrain adaptability through a multi-degree-of-freedom adjustment mechanism on the nozzle angle adjustment arm 1: when encountering slopes, the telescopic structure extends the adjustment arm to compensate for height differences, and the rotating connection adjusts the spray direction; in uneven areas, the telescopic length and rotation angle of each nozzle are adjusted in stages to maintain the optimal spray angle for all nozzles. A locking mechanism 13 ensures structural stability after adjustment, preventing displacement during irrigation. The water distributor 2, combined with a flexible hose system, allows independent adjustment of each nozzle without affecting the overall water pressure balance. The three-point positioning structure of the support frame, combined with spiral ground stakes, establishes a stable foundation on soft or sloping ground, ensuring structural rigidity when the adjustment arm supports the nozzles. The multi-nozzle coordinated adjustment mechanism allows the irrigation range to change with terrain undulations, ensuring uniform water mist coverage.

[0034] like Figure 2 As shown, in one embodiment, the telescopic structure 11 of the nozzle angle adjusting arm 1 of the high-efficiency corn irrigation device of this application consists of an outer cylinder 6 and an inner rod 7 forming a nested assembly relationship. Specifically, the outer cylinder 6 is a hollow tubular component with multiple equidistantly arranged limiting holes spaced along its axial direction on its wall, while the inner rod 7 is a solid rod design with a spring-loaded locking pin 8 at its end. When the inner rod 7 slides along the axial direction of the outer cylinder 6, the locking pin 8 can be inserted into any of the limiting holes under the action of the spring, forming a discrete positioning mechanism. This structure achieves linear length adjustment through the relative displacement of the inner rod 7 and the outer cylinder 6, while providing rigid fixation through the engagement relationship between the limiting holes and the locking pin 8.

[0035] Furthermore, the outer cylinder 6 and inner rod 7 employ a polygonal cross-section design to restrict circumferential rotation, ensuring that only axial displacement occurs during adjustment. Limiting holes are spirally distributed on the surface of the outer cylinder 6, allowing the locking pin 8 to maintain a perpendicular engagement angle at different extension lengths. The front end of the inner rod 7 is equipped with an anti-disengagement ring that engages with an annular groove on the inner wall of the outer cylinder 6 to prevent excessive stretching from causing component separation. During operation, pressing the locking pin 8 releases the limiting state, and releasing the locking pin 8 after adjustment to the desired length achieves automatic locking.

[0036] For example, a specific embodiment of the telescopic structure 11 is as follows: the outer cylinder 6 is fixed to the base end of the nozzle angle adjusting arm 1, and the end of the inner rod 7 is connected to a rotatable connecting part. During adjustment, the operator pulls the inner rod 7 outward to disengage the locking pin 8 from the current limiting hole. When it extends to the limiting hole position corresponding to the target length, the locking pin 8 automatically engages in the hole under the action of the spring return force. The mating surfaces of the outer cylinder 6 and the inner rod 7 are coated with a low coefficient of friction, and a waterproof sealing ring is installed at the joint to ensure smooth sliding and rust prevention.

[0037] like Figure 1 and Figure 2As shown, in one embodiment, the rotatable connection part 12 of the nozzle angle adjusting arm 1 of the high-efficiency corn irrigation device of this application adopts a multi-degree-of-freedom ball joint structure, which includes a spherical head 9 and a spherical seat 10 that cooperate with each other. Specifically, the spherical head 9 is a hemispherical protrusion structure with an annular positioning groove machined on its outer surface, while the spherical seat 10 is a concave hemispherical cavity with a limiting protrusion corresponding to the positioning groove on the inner wall of the cavity. The two are assembled by interference fit, wherein the spherical head 9 is constrained within the slidable contact surface of the spherical seat 10, forming a composite kinematic pair that can both rotate around the axis and tilt. This ball joint structure is integrated at the connection node between the nozzle angle adjusting arm 1 and the fixed support frame 3, and its spherical seat 10 is rigidly connected to the support frame through a flange, while the spherical head 9 extends a connecting rod and is fixedly connected to the main structure of the adjusting arm.

[0038] To achieve reliable angle holding, the locking mechanism 13 includes a constraint ring fitted around the outer periphery of the spherical seat 10. This constraint ring, through a threaded pair, allows for axial displacement adjustment with the spherical seat 10. When the constraint ring is tightened, its inner conical surface compresses the spherical seat 10, causing elastic deformation and increasing the clamping friction on the spherical head 9. Specifically, the axially split design of the spherical seat 10 gives it radially contracting elastic deformation capability, and the advance of the constraint ring can be quantitatively controlled via scale markings. This structure allows the operator to fix the three-dimensional spatial pose with a single locking action after completing multi-directional angle adjustments.

[0039] For example, the ball joint structure can be integrally formed using a metal casting process. The ball head 9 is made of 304 stainless steel, precision machined, and chrome-plated to reduce the coefficient of friction. The ball seat 10 is made of copper alloy, with annularly distributed grease reservoirs machined into its inner cavity, and PTFE wear-resistant gaskets embedded in the contact surface. The locking mechanism 13 can be a screw-type sleeve with anti-slip texture, and the outer edge of the sleeve has angle indicator marks, which, together with the reference scale lines on the support frame, form a visual adjustment reference system. During assembly, the ball head 9 and the connecting rod of the adjusting arm are fixed by a double method of transition fit and radial pins to ensure the reliability of torque transmission.

[0040] like Figure 2As shown, in one embodiment, the locking mechanism 13 of a high-efficiency corn irrigation device of this application includes a mechanical locking assembly consisting of an adjusting knob 23 and a locking screw 19, which form an axial displacement control structure through threaded engagement. Specifically, the adjusting knob 23 is arranged at the outer operating end of the nozzle angle adjusting arm 1, and its inner hole is provided with a threaded structure that matches the locking screw 19. The locking screw 19 extends along the axial direction of the adjusting knob 23 into the interior of the spherical bearing. The end of the locking screw 19 is provided with a tapered pressing surface, which forms a contact engagement with the spherical surface of the spherical head 9. The spherical head 9 is fixedly connected to the end of the rotatable connecting part 12 and is constrained in the spherical cavity of the spherical bearing. When the adjusting knob 23 is rotated, the locking screw 19 generates axial displacement, and radial pressure is applied to the spherical head 9 through the tapered pressing surface, thereby achieving frictional locking between the spherical bearing and the spherical head 9.

[0041] For example, the locking mechanism 13 can be machined to form a locking screw 19 with trapezoidal threads. The adjusting knob 23 uses a plastic handle with anti-slip texture, and a copper threaded sleeve is embedded inside. The spherical head 9 is connected to the metal rod of the rotatable connecting part 12 by welding. The spherical bearing adopts a split structure and is assembled on the mounting base of the fixed support frame 3. During operation, rotating the adjusting knob 23 clockwise will push the locking screw 19 into the spherical bearing, and its end conical surface will press the spherical head 9 against the inner wall of the spherical bearing, thereby increasing the friction of the contact surface to achieve angle locking.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the water distributor 2 of a high-efficiency corn irrigation device of this application includes multiple water outlet ports 14. These ports are arranged on the surface of the distributor housing at a preset spacing and distribution, forming a multi-path diversion structure. The axial direction of the water outlet ports 14 is arranged perpendicular to or at an inclined angle to the axis of the distributor body, and their inner diameter is designed differently according to the water pressure and flow requirements of the irrigation area. Specifically, the ends of the water outlet ports 14 are equipped with standardized threaded interfaces or quick-connect structures to achieve a reliable sealed connection with the connecting hose 5. The distributor has a water distribution cavity inside, and the inner wall of the cavity is provided with guide ribs or conical diverters to balance the water pressure distribution of each water outlet port 14.

[0043] For example, the housing of the water distributor 2 can adopt a cylindrical or rectangular cross-section structure, with six water outlet ports 14 arranged in a ring array or linear pattern along the axial direction on its circumferential surface. Each port has a metal connector seat with a sealing ring embedded in it. The inner part of the water distribution chamber has a two-stage flow guiding structure: the front section is equipped with a conical contraction section to accelerate the water flow, and the rear section is equipped with a cross-shaped flow guide plate to evenly divide the water flow into multiple branches. Each water outlet port 14 is connected to a pressure-resistant polyethylene hose by a threaded connection to achieve a sealed connection. The end of the hose is fixed in a pre-set groove on the surface of the distributor housing by a clamp.

[0044] like Figure 2 and Figure 3 As shown, in one embodiment, the water distributor 2 of a high-efficiency corn irrigation device of this application includes multiple parallel water outlets 14, each with an independent flow regulating valve 15 at its outlet end. The flow regulating valve 15 is integrated axially in series within the fluid channel of the water outlet 14, and its valve body forms a sealed fit with the water outlet 14 via a threaded connection. Each flow regulating valve 15 includes a linearly displaceable conical valve core, an adjusting knob 23 linked to the valve core, and a limiting locking assembly. The adjusting knob 23 is exposed on the housing surface of the water distributor 2 for easy manual operation. The axial movement of the valve core changes the flow cross-sectional area of ​​the water outlet 14. This structure allows operators to individually adjust the water output of the corresponding water outlet 14 according to the different water demands of different irrigation areas, while ensuring the independence of the water pressure in each branch.

[0045] Specifically, the flow regulating valve 15 is implemented as follows: the valve body has an internally threaded connection section coaxial with the outlet port 14, and a valve core seat with a guide groove is installed inside. The conical valve core slides against the valve core seat through a precision-machined guide protrusion. The adjusting knob 23 passes through the housing of the water distributor 2 via a waterproof bearing, and its end is rigidly connected to the valve core through a pin. The outer edge of the knob is provided with anti-slip texture and flow scale markings. When the adjusting knob 23 is rotated, the valve core is displaced along the axis of the outlet port 14, and the flow rate is linearly adjusted by the change in the annular gap between the conical surface and the valve seat. The limit locking assembly includes a spring-loaded ratchet mechanism, which can achieve self-locking fixation at any adjustment position. This structure ensures that the flow parameters remain stable under vibration conditions, while facilitating precise flow grade control.

[0046] The fixed support frame 3 adopts a triangular frame design, consisting of three legs 16 arranged in a spatial triangle. The legs 16 are connected by a top connecting plate, forming rigid nodes. This geometric configuration ensures lightweight construction while improving anti-overturning stability. Each leg 16 has an adjustable anchor bolt 17 at its end, which includes a threaded adjustment section and a ground contact plate. The threaded adjustment section forms a helical pair with the internal thread at the bottom of the leg 16, allowing for millimeter-level fine-tuning of the leg 16 length by rotating the adjustment rod. The three adjustment points form a non-collinear support plane. Combined with a level detection device, the support frame can be corrected for three-axis posture, ensuring the irrigation device is installed horizontally on slopes or uneven ground.

[0047] like Figure 4 As shown, in one embodiment, the fixed support frame 3 of the high-efficiency corn irrigation device of this application adopts aluminum alloy tubular legs 16 arranged in an equilateral triangle. Each leg 16 has an M20 internal thread interface machined at its bottom end. The screw portion of the adjustable anchor bolt 17 has a matching external thread and extends into a hexagonal adjusting head. A circular load-bearing steel plate with a diameter of 100mm is welded to the bottom of the bolt. During installation, by rotating the adjusting head of each leg 16, the screw is axially displaced under the threaded engagement. When the bubble on the level gauge at the bottom of the anchor bolt is centered, the level calibration of the support frame is completed. The adjusting mechanisms of each leg 16 operate independently, allowing for height compensation of individual support points, thereby adapting to local depressions or convexities in the field.

[0048] like Figure 4 As shown, in one embodiment, the fixed support frame 3 of the high-efficiency corn irrigation device of this application is provided with anchor bolts at the bottom, and the bottom end of the anchor bolts is provided with conical spikes 18. Specifically, the conical spikes 18 and the ends of the anchor bolts are connected by threads or welded to form an integrated structure. The outer surface of the spikes 18 can be designed as a continuously tapering cone or pyramid, with the cone angle controlled within the range of 15°-30° to achieve progressive penetration. The sidewalls of the conical spikes 18 can be provided with spiral guide patterns or barbed structures. The former is used to reduce soil compression resistance, and the latter is used to enhance pull-out resistance. The top of the anchor bolts is rigidly connected to the bottom of the support frame column through a flange to form a vertical force transmission path. When the support frame is subjected to external forces, the conical spikes 18 increase the contact area and frictional resistance with the surrounding soil, thereby improving the device's anti-overturning ability in soft soil.

[0049] For example, the conical spike 18 can be made of high-strength alloy steel, with a helical cutting edge at its tip. The threaded section accounts for 2 / 3 of the total length of the cone, and a reverse barb ring is provided at the tail end. During installation, the conical spike 18 is screwed into the soil by rotating the anchor bolts. The helical cutting edge effectively breaks up soil particles, while the barb ring forms a mechanical interlock with the surrounding soil after being fully buried. This structure allows the support frame to maintain the predetermined burial depth when subjected to the vibration of the irrigation system, while the wedging effect of the conical spike 18 disperses the load and prevents local soil collapse.

[0050] like Figure 2 As shown, in one embodiment, the adjustable nozzle 4 of the high-efficiency corn irrigation device of this application also integrates a pressure sensing module 20. This module includes a pressure sensor and a signal processing unit. Its main structure is embedded near the internal flow channel of the nozzle and isolated from the water flow channel through a sealed interface. The pressure sensor is arranged along the water flow direction at the nozzle inlet section, and its detection end is in direct contact with the fluid to obtain dynamic pressure data. The signal processing unit is connected to the sensor through a waterproof cable and converts the analog signal into a digital signal. The main control module is located in the control box inside the fixed support frame 3. It forms a closed-loop communication with the pressure sensing module 20 through a data cable, receives pressure data in real time, and performs threshold comparison. The indicator light assembly includes multi-color LED beads, which are installed in the groove on the top of the nozzle shell and connected to the main control module through a flexible circuit board. Different colors are triggered according to the pressure status.

[0051] Specifically, a sensor mounting cavity can be machined into the aluminum alloy substrate of the adjustable nozzle 4, and a piezoresistive pressure sensor can be embedded in the cavity with its sensing diaphragm facing the water flow direction. The sensor output is connected to the ADC conversion interface of the main control module via an RS485 bus. The main control module presets a pressure threshold range. When the detected value is lower than the set lower limit, the indicator light switches to a solid red mode; when it is within the normal range, it displays a green breathing light mode; and when it exceeds the upper limit, it switches to a flashing red alarm. A polytetrafluoroethylene (PTFE) isolation membrane is installed between the sensor cavity and the nozzle flow channel to ensure both pressure transmission and electrical isolation.

[0052] In irrigation systems, the connecting hose 5, serving as a flexible water delivery channel, must balance deformation adaptability with structural reliability. This design utilizes an elastic corrugated pipe material to construct the pipe body. Its axial corrugated structure endows the pipe body with excellent radial flexibility and axial expansion and contraction capabilities, adapting to displacement changes caused by the movement of the nozzle angle adjustment arm 1. To enhance tensile strength, a multi-level annular reinforcing ring 21, evenly distributed along the axial direction, is integrated in the middle of the pipe body. Each reinforcing ring forms a composite structure with the corrugated pipe matrix through a molding process. The reinforcing rings are constructed from layers of high-molecular polymer and fiber-reinforced composite materials. The inner layer forms an embedded connection with the outer wall of the corrugated pipe, while the outer layer is covered with a weather-resistant protective coating, creating a gradient strength distribution. This structure maintains overall flexibility while effectively preventing pipe tearing caused by frequent bending or mechanical traction through the distributed bearing effect of the reinforcing rings on longitudinal tensile forces.

[0053] In one embodiment, the connecting hose 5 of the high-efficiency corn irrigation device of this application is manufactured using a three-layer co-extrusion process: the inner layer is a polyethylene corrugated pipe containing an antistatic agent, the middle layer is embedded with equidistantly distributed polyester fiber reinforcing rings as reinforcing rings, and the outer layer is coated with an ultraviolet-stabilized polyurethane coating. The reinforcing rings are evenly distributed in the middle section of the pipe body at 15cm intervals and are molecularly bonded to the inner corrugated pipe through a hot-melt composite process, with flexible corrugated sections retained between adjacent reinforcing rings. Flange-type quick connectors are provided at both ends of the pipe body to form a sealed snap-fit ​​connection with the output end of the water distributor 2 and the inlet end of the adjustable nozzle 4, respectively. The flange edge is provided with anti-torsion ridges to ensure accurate pipe installation direction.

[0054] like Figure 2 and Figure 3 As shown, in one embodiment, the nozzle angle adjusting arm 1 and the water distributor 2 of a high-efficiency corn irrigation device of this application are detachably connected via a quick connector 22. The quick connector 22 is located between the end of the adjusting arm and the water distributor interface, employing an axial plug-in structure, and includes mating snap-fit ​​components and sealing components. Specifically, the connector body is composed of a corrosion-resistant metal ring, with an integrated annular sealing ring inside to ensure watertightness at the connection point. Two sets of spring-loaded locking snaps are symmetrically arranged on the outside, and the snaps are engaged and released by rotating the locking ring. This connection method allows the operator to tighten the connector without tools by rotating the locking ring clockwise, and to quickly separate the components by rotating it counterclockwise.

[0055] For example, the quick connector 22 can adopt a split-type structure design, where the end of the adjusting arm has a plug-in end with a guide flange, and the corresponding position of the water distributor 2 forms a matching tapered receiving interface. The outer wall of the plug-in end is provided with an annular groove. When inserted into the receiving interface of the distributor, the locking ball is engaged in the groove under the action of a spring, forming a mechanical lock. The connector is internally equipped with double-layer silicone sealing rings, located on the inner and outer sides of the water flow channel, respectively, to ensure no leakage when high-pressure water flows through. During maintenance, simply press the release button of the locking ring and rotate it 30 degrees to release the locking engagement, allowing the adjusting arm to be separated from the distributor for component replacement or cleaning.

[0056] In actual operation, when this device is used, the length of the nozzle angle adjusting arm 1 is first adjusted by the telescopic structure 11 of the nozzle angle adjusting arm 1 to adapt to the terrain requirements of different areas. Then, the spray direction is changed by its rotatable connecting part 12, and the adjusted angle is locked securely by the fixing locking mechanism 13. The water flow distributor 2 evenly distributes the external water source to multiple connecting hoses 5. The water flow is transmitted to the adjustable nozzle 4 through the hoses to form a spray flow. The fixed support frame 3 continuously provides stable foundation support, so that the nozzle angle adjusting arm 1 and the adjustable nozzle 4 maintain the preset spray posture. Finally, the efficient irrigation of cornfields with different terrains is achieved through the spray coverage with the angle adapted.
